CAOCAP is a creative canvas for building real software, one small project at a time. It's for designers, founders, students, and anyone with an app idea — no coding background required. Inside CAOCAP, you build real Mini-Apps: small, working pieces of software you can run and see come to life — not toy exercises or throwaway demos. Each mission teaches something real — layout, state, logic, data, debugging, or architecture — right when you need it. CoCaptain is your AI mentor, not a generator. It writes, edits, and debugs alongside you, but its real job is helping you understand what's happening underneath, so you leave every mission more capable than when you started. You don't just end up with an app. You end up better at building them. What you get: • A spatial canvas where you build, run, and inspect real projects • Guided missions that teach one concept at a time, as you need it • CoCaptain, an AI mentor that explains and edits code without taking over • Instant live previews of everything you build • Hands-on practice with HTML, CSS, and JavaScript CAOCAP isn't another prompt-to-app tool that generates something for you and hopes it works. It's a way into software that stays yours the whole way through. Unlock CAOCAP Pro for unlimited missions and full access to CoCaptain.

Read full description

The best app to calculate all quantities of an arbitrary triangle. You must enter some quantities like two angles and one length. The algorithm searches the formulas of the missing quantities, shows them and calculates the results. The length of the decimal place can be changed. The algorithm shows when rounding or wrong values lead to an opposition. Decimals and fractions are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared. [ Contents ] - all important quantities for the arbitrary triangle - formulas for all important quantities of an arbitrary triangle - infographic to illustrate the topic - search bar to find the desired quantity - history function to save the input - detailed solution - positive numbers, decimals and fractions are supported - no ads! [ Usage ] - there are fields for entering values using a special keyboard - press the check mark button at the bottom right to start the calculation - if values are missing, all fields will be marked orange - if the values are wrong (e.g. negative lengths), the affected field will be highlighted red - if a value is no number, it is highlighted in red - the entries in the history can be deleted or sorted - if you select an entry in the history, it will be automatically loaded for the calculation - the whole history can be deleted by pressing a button - solutions can be shared [ Math conditions ] - each value must be greater than zero - each angle must be less than 180° - the sum of two sides must always be greater than the length of the third side
